I have no objection. Please use endfor instead of end to end the loop.

Hello,

Marco Caliari has proposed to use Horner's method in polyval.m (see bug #31098) as in the attached changeset.

It improves performance and makes polyval consistent with ppval (which already uses Horner's method).

Is it ok to push this?

Thanks and regards

Thorsten
